S1117-xxPI
Fixed LDO Voltage Regulator
Descriptions
The S1117 series of positive fixed regulators are designed to provide 1A with higher
efficiency than currently available devices. All internal circuitry is designed to operate
down to 700mV input to output differential and the dropout voltage is fully specified as a
function of load current. Dropout voltage of the device is 100mV at light loads and rising to
700mV at maximum output current. A second low current input is required to achieve this
dropout. The S1117 can also be used as a single supply device.
Features
• Output Current of 1A
• 1.3V Maximum Dropout voltage at 1A Output Current
• 100% Thermal Limit Burn-In
• Fast Transient Response
